Breather Valve

Details

PV relief valves are safety equipment designed to protect tank against rupturing or imploding. As long as the tank pressure remains within the valve pressure and vacuum setting the pallets remains in contact with the seat ring and no venting or breathing take place. If direct atmosphere discharge or nitrogen is used on vacuum inlet, a flanges connection is available.
PV relief valve is commonly referred to as a “breather valve” because of its primary function.
Flame arrestor can be mounted directly upstream of breather vent.

• new shape for fluid dynamic improvements
• pipe away connection on Pressure and process side
• pallet guide outside the process

Emergency Vent

Details

Sized to provide emergency relief due to over-pressure from tank inside.
When internal pressure is beyond the capacity off breather vent.
